Module:HtmlBuilder/doc
This is the documentation page for Module:HtmlBuilder
HtmlBuilder provides a way to construct complex HTML and CSS markup by creating a tree of nodes, similar to the Document Object Model. The result is code that is more comprehensible and maintainable than if you simply concatenated strings together. It offers a fluent interface that should look familiar to any user of jQuery.
Usage
First, you need to load the module:
local HtmlBuilder = require('Module:HtmlBuilder')
Next, create the root HtmlBuilder instance:
local builder = HtmlBuilder.create()
Then, you can build HTML using the methods of the HtmlBuilder instance, listed below.
Finally, get the resulting HTML markup as a string:
local s = tostring(builder)
Methods
To allow chaining, all methods return a reference to the builder, unless otherwise stated.
tag
local div = builder.tag('div')
Appends a new child node to the builder, and returns an HtmlBuilder instance representing that new node.
done
builder = div.done()
Returns the parent node under which the current node was created. Like jQuery.end, this is a convenience function to allow the construction of several child nodes to be chained together into a single statement.
allDone
builder = div.allDone()
Like .done()
, but traverses all the way to the root node of the tree and returns it.
wikitext
div.wikitext('This is some [[example]] text.')
Appends some markup to the node. It may include plain text, wiki markup, and even HTML markup.
newline
div.newline()
Appends a newline character to the node. Equivalent to .wikitext('\n')
.
attr
div.attr('title', 'Attr value')
Set an HTML attribute on the node.
css
div.css('color', '#f00')
Set a CSS property to be added to the node's style
attribute.
cssText
div.cssText('color:#f00; font-size:1.5em')
Add some raw CSS to the node's style
attribute. This is typically used when a template allows some CSS to be passed in as a parameter, such as the liststyle
parameter of {{Navbox}}.
addClass
div.addClass('even')
Adds a class name to the node's class
attribute. Spaces will be automatically added to delimit each added class name.
Examples
<syntaxhighlight lang="lua"> local HtmlBuilder = require('Module:HtmlBuilder')
local root = HtmlBuilder.create()
root
.wikitext('Lorem ') .tag('span') .css('color', 'red') .attr('title', 'ipsum dolor') .wikitext('sit amet') .done() .tag('div') .wikitext('consectetur adipisicing')
local s = tostring(root)
-- s = 'Lorem sit amet
'
</syntaxhighlight>
